This'inventionrelates to automobile trailers,

and has particular reference to a trailer adapted to handle boats. An object of the invention is to generally improve trailers, and to provide a device of the character indicated-which is simple in constrution, economical to manufacture, andefficient in operation.

Another object-of the invention-is the provision of altrailer which is constructed and arranged whereby a boat may be lifted from the water or 01f of the ground and may be transported from .n q t a sion of a device of the character-indicated, which is provided with independent wheel suspension construction and arranged to provide great flexibility' to the device when the latter is drawn over uneven terrain.

Another object of the invention, is the provision of a trailer for handling boats and the like which is provided with independent wheel suspension capable of withstanding extremely heavy thrusts.

The foregoing and other objects and advantages of the invention will become more apparent as the description proceeds, reference being made from time to time to the accompanying drawings, forming part of the within disclosure, in which drawings:

Fig. 1 is a top plan view of a device embodying the invention.

Fig. 2 is a view partly in section taken on the line 2-2 of Fig. 1.

Fig. 3 is a. section taken on the line 3-3 of Fig. 2.

Fig. 4 is a section taken on the line 4-4 of Fig. 3.

Fig. 5 is a section taken on the line 55 of Fig. 2.

Referring now more particularly to the drawings, it will be understood that in the embodiment herein disclosed, the device consists of a pair of tubular members I and 8, bent and rebent as shown in Fig. 1, to form a frame closed at the front-9 and openat the rear, as at ID. A tow plate H is preferably welded to' the front ofthe frame 9 so thatth'e deviceimay be secured to the bumper l2 (Fig.2) of an automobile, or the-like. A single spar like riser !3, preferably comprising a hollow tubular member of square cross'section, is welded or otherwise secured to the front end of the frame, as at l4. I i

The spar i3 is reinforced by means of braces [5, which extend'between thespar i3 and the respective frame members I and 8. A winch-13A is supported on the spam, and is adapted-to handle the cable I3B.

An inverted U-shaped member comprisinga cross member l6- and supporting legs ISA and 16B are secured-to theiramemembers land '8 by welding or'other suitable means, and are reinforced by braces I1, l8, I9 and 2%. Lugs 21, 22, 23, and 24 arepreferablywelded to the rear of the cross member I6, and are provided with central openings through which: is extended a pipe ior rod '25, which is adapted to be rotated .by the crank 26 to serve as a plural winch, whereby the cables'2'! and 28 may be wound there about; .A ratchet 29 is provided'tolock'the member 25 in anydesired position."

Removable: and adjustable crossmembers 30 and 3| are' 'suspe'nded' beneath theframe memhers I and B'by means of bolts 32 and win -nuts 33. The members 30 and 3! preferably consist of angle irons 30A and 3IA and wooden strips 303 and 3IB. The wing nuts 33 (Fig. 5) preferably consistof a tubular member closed at the bottom to protect the threaded ends of the bolts 32.

The frame assembly is supported by rubber tired wheels 34 and 35 which are independently suspended from the member 1 and 8 respectively as hereinafter described.

Dependin from each member 1 and 8 is a hanger 36 (Fig. 2) which preferably consists of a plurality of plates secured by welding or other suitable means to the underside of each frame member I and 8. Each hanger 36 (Fig. 4) is provided with openings adapted to accommodate a bushing 31, which is arranged to engage the pivot pin 38 about which is adapted to pivot an arm 39. -A wheel spindle 40 is secured to each arm 39, and is adapted to rotatably support a wheel. A stop member 4| is positioned on the underside of each hanger 36, and is adapted to limit the downward movement of the arm 39. A coil spring 42 (Fig. 2) is interposed between the end of the arm 39 and the frame member 8. The spring 42 is prevented from being displaced by and desire, 'to J secure by Letters Patent means of a retainer 43 carried at the end of the arm 39, and a cup like member 44 carried on the frame member 8.

Although I have described one of the independent wheel suspension mechanisms, it will be understood that each wheel is suspended in the same manner. Each wheel is covered by means of a mud guard or fender 46.

In order to use the device, the cross members 30 and I "are {first removed, and "the %frame {is backed-over the-boa? so that the "bow of the boat is near the spar member l3, and the stern and means "cooperatingbetween said arm and of the boat is as near to the cross member lfi' as possible. made fast to rings or other suitable means pro- The cables I313, 21 andg28care then eomhin'ationfia frame consisting of a pair of boat has been lifted from its resting place on the ground or in the water, the members 3'fl-"an'd 3L- are then secured in position, and the boat 45 may; be lowered: on to'rthem for; rigid support during'itransportationu, V
